INVENTOR. RICHARD J. HARWOOD ATTORNEY United States Patent 3,134,378 EXERCESE RIACHINE Richard J. HHIWOOd, 1 Hawthorne, Wichita, Kans. Filed Get. 10, 196i Ser. No. 61,746 14 Claims. (Cl. "1223-) This invention relates to exercise machines. In a more specific aspect, this invention relates to bicycle type exercise machines having power means to drive pedals and oscillate hwdle bar and seat structures. In another aspect, the invention relates to means for driving the movable structure in an exercise device.

Various types of exercising machines, including the socalled bicycle type exerciser are known. The bicycle exercisers of the prior art utilize spring or other means as a counter-balance for the weight of the individual using the machine, and these means have been found to be unreliable in operation, such tending to lose their strength, thus reducing the efiectiveness and eihciency of the bicycle exerciser. Also, prior art bicycle type exercisers have failed to provide suitable adjustable handle bar and seat supporting structures which are desirable for the device to be conveniently used by persons of diflerent size and/or weight. Furthermore, the prior art devices do not provide means for positively preventing movement of the device on the supporting surface during operation, resulting in slippage and in some instances damage to the supporting surface which limits use of these devices in the ordinary home. The mechanical means for operating the prior art bicycle type exercisers are bulky, inefficient and unreliable. Also, the moving parts operating the exercising device are often not shielded or covered, thereby requiring care in use so as to prevent injury. Many of the prior art devices, particularly those having counter-balance means, cannot be operated unless driven by the power means since the force required to operate the device is greater than can be supplied by a human being. This limits the use of the device and requires excessively large and expensive power units.

In accordance with the present invention a new exerciser has been provided which overcomes the disadtages and deficiencies apparent in the prior art. The present bicycle type exerciser utilizes an improved mounting means which positively prevents uncesirable movement of the device during operation. Also, the handle bar and seat structure are adjustable and variable within a wide range so that the device can comfortably be used by various individuals, regardless of s ze or weight. New and improved mechanical operating means are provided in each of several preferred embodiments which efiiciently provides for the desirable interaction between the foot pedals and the seat and handle bar structures. The moving parts of the apparatus of the invention are preferably covered so that injury to the user due to movement of any of the apparatus is prevented. The present machine is constructed so that it can be operated without the power means, it more versatile and eliminating the need for excessively large power means.

One preferred specific embodiment of the exerciser of the invention includes a base. The base is preferably supported by feet and/or wheels which are desirably constructed in such a manner as to prevent movement of the base during operation of the apparatus. Seat ""ld handle bar structures are preferably constructed and mounted so as to be movable relative to each other and in relation to foot pedals. Power means are desirably provided and suitably mounted so as to drive the foot pedals, seat structure, and handle bars. Various mechanical means of my invention for driving the seat, foot pedals and handle bars are provided to obtain the desired results. The device is preferably covered with a housing which covers the working parts.

The mechanical means of the invention for" driving an exerciser is preferably applied to an exerciser having a foot pedal crank assembly rotatably mounted on suitable frame means, and a handle bar post assembly and a seat post assembly carried by the frame means. In the drive means of my invention these assemblies are operatively connected thereby so that the seat post assembly and handle bar post assembly are moved when the foot pedal crank assembly is rotated. Preferably, this movement occurs whether the preferred electric powered means drives the foot pedal crank assembly or whether same is manually powered. In a specific preferred embodiment, a sprocket havin an eccentrically mounted pin thereon is carried by the frame means and is driven by a sprocket on the foot pedal crank assembly. Linking means, such as a pitman, is carried by the pin to impart an oscillating movement to the seat and handle bar post assembly. In some of the preferred embodiments of the mechanical driving of the invention, a single pitman is used and the handle bar and seat post assemblies are interconnected by suitable linking means. In other specific embodiments of the invention, a plurality of pitmans are used to impart the motion to the seat and handle bar post assemblies. In one preferred specinc embodiment of the mechanical drive means of the invention, two pitmans are preferably used to act in unison to impart the oscillating movement to the handle bar and seat post assemblies.

The following is a discussion and description of preferred specific embodiments of the new exerciser of the invention, and the new mechanical operating means of my invention, such being made with references to the drawings whereon the same reference numerals. are used to indicate the same or similar parts and/ or structure. It is to be understood that such discussion and description is not to unduly limitthe scope of the invention.

Referring now to the embodiment of the invention shown in FIGS. 1-9, the bicycle type exercising machine of the invention includes an elongated base member 20 which is preferably somewhat wider at the rear end portion than at the forward end portion so as to form a generally T-shaped base member. Base member 20 is also preferably inclined upwardly fiom the rear end portion to the front end portion and has ledges 22 and 24 along the intermediate and forward end portions to receive and mount frame members described hereinafter. An upper housing 26 is desirably provided and is preferably contoured as to cover all of the working or moving parts of the exerciser to prevent the possibility of the user becoming injured by the moving parts. Housing 26 can be mounted on base 20 in any suitable manner, such as by providing a ridge 30 around the periphery of base 20 on which housing 26 will snugly fit. Base 20 and housing 26 can conveniently be formed of metallic or plastic materials and can be reinforced if desired to provide the required strength. A fiberglass reinforced plastic housing has been found desirable.

Base member 20 preferably has an elongated, generally arcuate recess 32 formed therein, preferably on one side by providing spaced feet 36 and 38 secured to opposite corners ofthe front portion of the basemember 20. FIG; 9 shows a desirable manner of mounting the feet 36 and 38 wherein foot 38 is bolted or otherwise secured to brace member 40 which in turn is secured to the corner of base 20 in any suitable manner, such as by glassing in as shown at 42. v

i The rear end portion of base 20 is preferably mounted on wheels and in such a manner that the exercise machine can be moved when desired but will be prevented from moving during operation. A preferred manner of doing this is shown in FIGS. 4, 6 and 7. Two axles 46 and 48 are provided and are spaced by reinforcing and spacing members 50 which are rigidly secured to the axles, such as by welding. The members 50 are secured to the base 20 by mounting bolts 52 or the like. Wheels 54 and 56 are rotatably mounted on opposite ends of axle 46 and wheels 58 and 60 are mounted on opposite ends of axle 48. Axles 46 and 48 are spaced relative to the sizes of the wheels so that the wheels on each axle are in tangential frictional contact with the wheels on the other axle and with the supporting surface. Thus, when the exercise machine is in operation any movement of the machine will be prevented due to the counter-rotating frictional engagement between the wheels and with the supporting surface. In order to move the device, itis merely necessary to raise base 20 by lifting handle 34 so that one set of wheels is out of contact with the supporting surface. This wheel mounting is also advantageous for use in moving the exercise machine on steps or the like where first one set of wheels and then the other will contact the steps, eliminating much of the bumping and the like usually necessary in order to move the machine up the steps. This wheel mounting means is shown and described more fully in the copending application Serial No. 58,4l4, filed September 26, 1960, and titled Wheel Mounting Means, now Patent No. 3,096,852. While this means of mounting the base 20 has been found desirable, other means can be utilized if desired.

Suitable power means, such as electric motor 64, is mounted on the rear end portion of the base 20 in any suitable manner, such as mounting bolts 66. Motor 64 preferably is positioned between the wheels supporting the rear end of the device. Pulley 68 is mounted onthe shaft of the electric motor 64. Motor 64 preferably has two or more speeds, or the output can be varied by using a rheostat.

Two generally triangular shapedframe members 70 and 72 are rigidly mounted on ledges 24 and 22 respectively in any suitable manner, such as by mounting bolts 71. Frame member 70 consists of a base portion 74, a forward portion 76 and a rearward portion 78 and frame member 72 includes base portion 75, forward portion 77 and rearward portion 79. Frame memebers 70 and 72 are constructed to be the mirror images of each other and are in facing relation when mounted. Frame members '70 and 72 can be formed of common angle irons or other suitable materials secured together in any desirable manner. The frame members 70 and 72 are disposed in generally parallel planes when mounted.

Two shafts 88 and 82 are mounted for rotation on frame members 70 and 72 in any suitable manner, such as in pillow blocks 84 and 86 respectively. Shafts and 82 extend between the base portion of frame members 70 and 72 and are generally parallel when mounted.

A pulley 88 is fixed to shaft 80 to turn therewith. Pulley 88 is disposed within recess 32 in base 20'and receives a V-belt 9b which is connected to pulley 68 on the electric motor 64 so that pulley 88 and shaft 88 are driven by the electric motor 64.

Sprockets 92 and 94 are mounted on shaft 80 and 82 respectively for rotation therewith. Sprockets 92 and 94 are connected by a chain 96 so that when shaft 80 is rotated by pulley 88 shaft 82 will also be rotated through the chain drive and sprockets.

Crank arms 100 and'102 have one end portion thereof secured to opposite end portions of shaft 82 and are secured thereto so as to extend from shaft 82 one hundred and eighty degrees apart. Foot pedals 164 and 106 are secured to the other end portion of crank arms 100 and 102 respectively. Pedals 104 and 106 can be of the conven-' tional bicycle'type pedal, or they can be of the type shown in copending design application Serial No. 61,579, filed August 1, 1960, titled Pedal or Similar Article, now Patent No. D. 191,091. The pedals 104 and 106 preferably have adjustable straps 107 which receive the foot of the user.

Another sprocket 110 is mounted on shaft 82 for rotation therewith. A crank shaft 112 is rotatably mounted in pillow blocks 114 on the forward portion of frame members 71', and '72. Crank sprocket 116 is mounted on crank shaft 112 and is driven by a chain 118 between it and sprocket 119. Crank sprocket 16 has a crank pin eccentrically mounted thereon which receives one end portion of a pitman 122. A pivot 124 is rotatably mounted on and extends between the upper end portion of the forward portions of the frame members and 72. Pivot 124 receives one end of a lever 126. The other end portion of lever 125 is pivotally connected to the other end portion of pitman 122.

Handle bar support member is rigidly secured to the outer end portion of lever 126 in any suitable manner, such as by welding. Handle bar support member 131) extends in an arcuate manner forwardly and upwardly to project out of a hole in housing 26. Spoke 137 can be provided to brace handle bar support member 139, and is rigidly secured to the handle bar support member 131) and to the pivot 124. A collar member 132 is rigidly secured to the outer end portion of handle bar support mernber 13-3 and telescopically receives handle bar 134. Handle bar 134 has handles 136 thereon and handle bar 134 can be rotated within collar 132 as shown in FIG. 6, so that the handles 136 can be moved toward or away from the user during operation. Handle bar 134 is preferably telescopically, rotatably and lockably secured within collar 132 in any suitable manner, such as shown in copending application entitled Adjusting Means, Serial No. 61,453, filed October 10, 1960.

Two spaced and generally parallel seat post guide tubes 1413 and 142 are rotatably secured in any suitable manner in one end portion to shaft 82 and extend upwardly and rearwardly therefrom between frame members 71 and 72 and on opposite sides of the lever 126 and handle bar support member 13a). Seat posts 144 and 146 are received in seat post guide tubes 14% and 142 respectively. Seat posts 144 and 146 are separated bya lug reset bar 148 which extends between and is rigidly secured to both of the posts. Coacting means are provided on the seat posts 144 and and seat post guide tubes 140 and 142 to lockably and adjustably position the seat posts within the tubes. A preferred manner of accomplishing this is set forth in detail in the copending application entitled, Positioning Means for Seat Structures and the Like, Serial No. 48,035, filed August 8, 1960, and now Patent No. 3,113,793. This structure is shown in FiG. '16 and includes a base member 159 which receives seat post guide tubes 149 and 142. Lugs 152 and 154 are pivotally mounted on base member 150 so that one edge thereof can be in biting engagement with the post 144 and 146 respectively into which the edges of lugs 152 and 154 are received. A generally U-shaped leaf spring member 161 is loosely positioned between lugs 152 and 154 and urges the edges of the lugs into biting engagement with post 144 and 146 during normal locking action.

In order to adjust the posts 144 and 146 upwardly, it is merely necessary to lift the seat 162 to which the seat posts 144 and 14-6 are rigidly secured. Lugs 152 and 154 will permit upward movement of the seat posts. When the posts are urged downwardly the edges of lugs 152 and 154 will be in biting engagement with the posts, thus preventing downward movement. In order to readjust the seat to a lower position, the seat is first pulled to its outermost position at which time the lugs 152 and 154 wil be engaged by the lower end of the grooves 156 and 153 respectively, causing them to be moved into a nearly vertical position where they will be held by the fiat end portions of spring 169. The seat post 144 and 146 can then be lowered without engaging the lugs 152 and 154 until the lugs 152 and 154 are engaged by the lug reset bar 148, which moves the lugs outwardly into the grooves 156 and 153 whereupon the body portion of spring member 160 will once again urge them outwardly into biting contact with the seat posts 144 and 146, and the seat 152 can again be adjusted upwardly to any desired position merely by lifting on the seat. While the locking and positioning means for the seat structure 162 as described above is preferred, various other means of adjusting or positioning the seat can be used, if desired.

Since seat 152 will be moved during operation of the exerciser, it is preferred to provide a movable closure means with the housing 26 so that the operating portion of the device is never exposed and fingers, clothes and the like Will not become caught in the operating mechanism. For this purpose, elongated slots 164 and 166 (FIGS. 1, 3 and 5) are provided to receive tubes 140 and 142 respectively. Two transversely extending rod guides 158 and 170 (FIG. 5) are secured to the underneath surface of the upper portion of the housing 26 and spaced therefrom. Plates 172 and 174, which can be formed of the same plastic material used to make housing 26, are apertured to receive the seat posts guide tubes 140 and 142 and are positioned between the top surface of the housing 26 and the guides 168 and 1711 so that as the seat posts guide tubes 149 and 142 move longitudinally within the housing 26 during operation, the plates 172 and 174 will also be moved within guide 1 58 and 170 so that the inside of the device having the moving parts therein will never be exposed.

The exercise machine is preferably constructed so that the seat 162 moves in opposition to and in cooperation with the handle bar structure 134. One manner of accomplishing this is best seen in FIG. 8 and includes a pivot 13 which is secured to and extends between the seat post guide tubes 149 and 142. A connecting member 182 is pivotally connected to and joins the pivot 184 and the intermediate portion of lever 126 so that as lever 126 is moved by pitman 122 causing handle bar support member 1311 to be moved, the seat post guide tubes 140 and 142 are also moved. FIG. 8 illustrates the various positions of the pitman 122, lever 126, handle bar support member 13%, and seat post guide tubes 140 and 142 during a cycle of the device. Thus, as seen in FIGS. 6 and 8, as the sprocket 116 is rotated the seat 162 will be moved forward as the handle bars 134 are moved rearwardly, and as seat 162 is moved rearwardly handle bars 134 will be moved foiwardly.

To use the device, plug 186 is connected to a suitable electric wall outlet and switch 188 on the top of housing 26, which is connected to motor 64 by cable 189, is turned to the on position which starts electric motor 64. Pulley 68 will then be rotated, causing pulley 88 to be turned,

which in turn drives shaft 81) and 82. The rotation of shaft 82 turns pedals 1114 and 1% and also turns sprocket 116. As sprocket 116 turns crank pin 120 thereon will be moved eccentrically around shaft 112 so that pitman 122 will oscillate longitudinally. Pitman 122 causes lever 126 to oscillate which moves handle bar support member 130 and handle bars 134 thereon as well as the seat structure 162 as hereinbefore described. When motor 64 has more than one speed or a rheostat or other suitable means is provided to vary the speed of rotation of the electric motor 64, switch 133 can be conveniently operated by the user to obtain the desired result. Timing means shown at 19% in FIG. 1, can also be provided to accurately control the length of time the machine is used, and can be a coin operatedtimingdevice, if desired.

In order to further vary the operation of the device, the seat 152 can be moved to a higher or lower position, which also moves the seat forwardly or rearwardly, and handle bar structure 134 can be moved so that handles 136 thereon are closer to or further away fromthe user, such as shown in the dotted lines in FIG. 6. Also, the user can grasp either the upper or lower handles 136 in use so as to vary the movement of his body during the cycle of the machine. Furthermore, since handle bar structure 134 is telescopically and adjustably mounted in collar 132, the handle bar structure can be moved inwardly or outwardly as desired.

. When electric motor 64 is operating, the user expends a relatively small amount of energy. Since the machine utilizes no springs or'weights for counter-balancing, the user can, if desired, turn motor 64 off and operate the machine by manually pumping foot pedals 104 and 106. A further preferred specific embodiment of the exerciser and mechanical drive means of the invention is shown in FIGS. 10 andll, wherein a modified drive and operating means are provided. In this embodiment, a generally horizontal base or frame member 200 is secured to an arcuate frame member 202.- Duplicate frame members similar to members 200 and 202 are provided and are spaced therefrom in a parallel plane to provide a support frame work. Frame members 200 and 202 are supported at the rear end of the device by axle 204 having wheels 206 at each end thereof and at the front end therer of by the lower end of frame member 202 which act as the feet for the front end of the device. The front end portion of frame member 200 and/ or 202 can'be joined by suitable braces (not shown).

Electric motor 208 is mounted between the rear end portions of frame members 200 and has a pulley 210 mounted thereon. Shaft 212 is rotatably mounted between frame members 200 and has mounted thereon pulley 214 which is driven by V-belt 216 which passes over pulleys 210 and 214; Also mounted on shaft 212 for rotation thereon is sprocket 218.

Another shaft 220 is rotatably mounted between port members 200 and has mounted thereon for rotation therewith sprockets 222 and 224. Chain 226 connects and drives sprocket 224 with sprocket 218 on shaft 212. Pedal crank arms 228 and'230 are mounted on opposite ends of shaft 220 and extend therefrom 180 degrees apart.

Pedals 232 and 234 are mounted on the outer ends of crank arms 228 and 230 respectively. Pedals 232 and 234 are preferably of the type shown in the before men tioned patent application, though other types can be used, if desired. a

A crank shaft 236 is rotatably mounted on frame mem-' bers 200, preferably between shafts 212 and 220, and has sprocket 238 secured thereto. Chain 240 connects sprockets 222 and 238. Crank pin 242 is eccentrically mounted on sprocket 238. The mounting and construction of sprocket 238 and crank pin 242 is similar to that shown and described above in connection with sprocket 116 and crank pin 120.

. Crank pin 242 carries pitmans 244 and 246. The outer end portion of pitman 246 has two spaced seat post guide tubes 248 pivotally secured thereto, only one of which is shown in the drawings. A seat post 250 is received by each of the guide tubes 248 and suitable adjusting and locking means shown at 252 can be provided to position the seat posts 250 within tubes 248. The locking means 252 can be of any suitable construction, such as that shown in FIG. 16 of the drawings. A seat 254 is mounted on the outer end of seat posts 250 and preferably is contoured for the comfort of the user.

Pitman 244has a handle bar support post 256 pivotally preferably adjustably received byadjusting means 264 on handle bar support 256.- Adjusting means 264 can be of any suitable type, such as that shown and described in connection with FIGS. 1-9 and described in the before mentioned copending application entitled Adjusting Means, Serial No. 61,453, filed October 10, 1960. Handle bar 260 ispreferably rotatable within post 256 so that handles 262 can be placed in the position shown in either the solid or the dotted lines in FIG; 10.

sup-

'with shaft 236.

The entire device is preferably covered by a suitable housing, such' as a fiberglass reinforced plastic cover mem-' her, and a switch (not shown) is conveniently mounted on the housing to operate electricv motor 208 and regulate the driving speed of same. Timing means can also be included as in theprevious embodiment so that the device can be operated a predetermined .length of time.

In operation, the electric motor 208 is started which turns' pulley 214 and rotates shaft 212; Sprocket 218 thereon will be turned, causing sprocket 224 and shaft 220 to be rotated, which drives pedals 232 and 234. As shaft 220 turns, crank sprocket 238 will be driven, causing crank pin 242 tobe moved in an annular path coaxial Pitmans 244 and 246 will thus be moved, causing seat post tubes 248 and handle bar support member 256 to be moved alternately from the position shown in FIG. 10 to that shown in FIG. 11. Here, as in the previous embodiment, the machine can be operated manually, if desired.

A still further preferred specific embodiment of the exerciser and mechanical means of this invention is shown in FIGS. -12 and 13. In this embodiment two spaced frame members 330, only one of which is shown in the drawings, are provided and the lower end portions thereof are connected by base frame .member 302. The lower rear end portion of frame members 300 receive axle 304; Axle 304 has a wheel 306 rotatably mounted on each end thereof. In some instances, it will be desirable to provide" wheels in tangential frictional engagement such as shown in FIG. 6 of the drawings. of frame members 300 are rigidly secured to a bar 308 which extends across the front end of the bicycle type exerciser and has feet 310 thereon at either end thereof, preferably covered with rubber cup supportsor the like to prevent movement and injury to the supporting surface. An electric motor 312 is mounted between the rear end portion of base frame members 302 and has a pulley 314 mounted on the drive shaft thereof. Three shafts 316, 318 and 320 are mounted on frame members 302 and are generally parallel to each other and in spaced relation. Each of the shafts can be rotatably' mounted in any suitable manner, such as by the use of pillow blocks as shown in the drawings.

Handle bar 356 preferably has two sets of spaced handles 35% and 3613 similar to those previously described, and pref-' erably handle bar 356 can be rotated within the neck 352 so that the handles 358 and 369 can be positioned toward or away from the user as shown in the dotted lines in FIG. 12. The adjusting means 354 can be similar to that described in connection with FIGS. 1 and 6, or it can be simply an adjustable collar surrounding neck 352, which is split at its outer end so as to be compressed by the collar to tightly grip the handle bar 356.

A seat post guide tube 362 is mounted on shaft 318 to be movable thereon and extends upwardly and rearwardly therefrom and is positioned between the beams of handle bar assembly 344. Tube 362 receives a seat post 364 which mounts seat 36-6. Seat post 364 is preferably adjustably mounted Within seat post tube 3&2 by adjusting means 368 of any suitable construction, such as that shown in FIG. 16 of the drawings which can easily be adapted for use with a single tube and post. in other instances, it will be desirable to provide the adjusting means 368 by merely spliting the upper end portion of the tube 362 and providing an adjustable collar therearound which can be ti htened when the seat post 364 is in the desired position.

tandard 379 is rigidly mounted on the intermediate portion of seat post tube 362 and extends outwardly therefrom. Connecting bar 372 is pivotally mounted at one end portion on standard 379 and is pivotally received at its other end portion by pivot 348 on handle bar assembly 344. Thus, the seat post guide tube 362 is connected to the handle bar assembly 344 for movement therewith as movement is imparted thereto by pitman 342 moving with crank pin 34!).

The switch mechanism 374 for operating electric motor 312 is conveniently mounted on the forward portion of handle bar assembly 344, or it can be mounted on a housing (not shown). The switching mechanism preferably is such that electric motor 312 can be operated on any of its speeds, and timing mechanism can be provided as in previous embodiments described so that the user can ride the device for a predetermined time.

In operation, switch 374 is turned to the operating position which starts electric motor 312. Motion is imparted to pulley 322 by ll-belt s24 and pulley 314. This motion is transmitted through shaft 316, sprocket 325 and chain 33-3 to sprocket 332 on shaft 320 to turn the sprockets thereon and rotates the pedals 335 and 337. Rotation of shaft 32%) imparts movement to crank plate 334% and the crank pin 346 causing handle bar assembly 344 to oscillate about pivot 350. At the same time, the seat is moved with and in opposition to the handle bar asembly due to the connection of connecting bar 372 between the handle bar assembly 344 and the seat post guide tubes 3&2. Here, as in previously described embodiments, the seat and handle bar mechanisms can be adjusted relative to each other both outwardly and forwardly so that the device is readily usable by persons of varying physical dimensions, and the seat and handle bar can be positioned at varying distances apart for a progressive increase in the amount of exercise or toning of the muscles of the individual from day to day.

FIGS. 14 and disclose a still further preferred specific embodiment of the mechanical means of the invention. The working parts shown in these two figures can be used in connection with any of the embodiments previously described, however such a construction has been found particularly desirable for use with the device as shown in FIGS. 197 FIG. 15 is similar to FIG. 8, and illustrates the difference between the two embodiments, therefore the supporting structure and the like shown in the first embodiment described would be the same or similar when using the mechanical movement illustrated in FIGS. 14 and 15.

A triangular frame consisting of members dill, 4493,

10 and 405 is preferably provided and is secured to a supporting base. Another frame (not shown) is disposed in a generally parallel plane and is the mirror image of the first mentioned frame. These frames can be formed of angle irons or other suitable materials.

A shaft 4% is rotatably mounted on the frame members 501 in any suitable manner, such as by the use of pillow blocks 492 and 494. Shaft 4% receives crank arms 4% and 468 at opposite ends thereof and extending therefrom 180 degrees apart. are secured to the outer ends of crank arms 4% and 4498 respectively. Pedals 41d and 412 can be of any suitable construction, such as that shown in my copending design patent application entitled Pedal, or Similar Article, Serial No. 61,579, filed August 1, 1960, and now Design Patent No. D. 191,091.

Crank shaft 414 is mounted for rotation on the frame members 4&3 in any suitable manner, such as by the use of pillow blocks 416 and 41S. Shaft 414 extends through these blocks. Shaft 4% has rigidly mounted thereon a sprocket 419 and crank shaft 414 has sprocket 211 thereon, the sprockets 4-19 and 421? being connected by a chain or belt 422 to drive crank shaft 414.

Crank shaft 414 extends through both of the pillow blocks 416 and 418 and arms 424 and 426 have one end portion thereof rigidly secured to the ends of shaft 414 for rotation therewith. Pins 4 28 and 430 are rigidly secured to the outer end portion of arms 42 iand 426. Arms 4,24 and 426 preferably are aligned, that is they extend outwardly from shaft 414 in the same transverse plane. One end portion of a pitman 432 is received by pin 42% and one end portion of a like pitman 434 is received by pin 4-36. The other end portion of pitmans 432 and 434 receive the ends of a rod 43%.

Two seat post guide tubes 438 and 4443 are provided and are pivotally mounted on shaft 4% for oscillation thereon. Tubes 438 and 44% are generally parallel and receive seat posts (not shown), preferably so as to be adjustable therein. The seat post guide tubes, seat posts and the mounting therefor can be similar to those shown in PZGS. l, 6 and 16.

A pivot 442 is mounted on the frame members 403 in any suitable manner, such as by pillow blocks 4%4 and 446. A handle bar support member 448 similar to handle bar support member in the embodiment shown in FIGS. 1-9 is provided. Spokes 454) and 452 are provided and have the end portion thereof rigidly secured to handle bar support member 448 and pivot 4%2 so as to brace or reinforce the handle bar support member.

Rod 436 preferably has a short bar 456 rigidly secured thereto and projecting outwardly therefrom. Bar 456 can be secured to rod 436 in any suitable manner, such as by welding. The innermost end of handle bar support member :43 has a slot therein as shown at 458 and best seen in FIG. 15. The split end 453 of handle bar support 443 has a mount ng pin or belt 46!) passing therethrough which also passes through bar 456 so as to mount handle bar support member 448 for movement with rod 436. This type of mounting is particularly desirable since it per mits a certain amount of play or movement between handle bar support member 448 and rod 436, thereby reducing strain or stress on the members. Handle bar support 448 can be secured to rod 436 by other suitable means if desired.

A pivot 462 is positioned between seat post guide tubes 43S and 44% and a connecting member 454 is pivotally connected at its ends to lever 452 and pivot 462. The handle bar support member 448 and seat post guide tubes 4-38 and 440 are thus connected together for simultaneous movement in opposition during use of the machine.

In operation, shaft 400 is driven in any suitable manner, such as directly from a power source, through intermediate reduction gearing such as shown in the previous embodiments, or by the user manually turning the pedals. As shaft 4% is turned, pedals 41d and 412 will be driven Pedals 410 and 4-12.

11 V and sprockets 419 and 429 will be rotated, turning crank pins 428 and 430 in an annular path about shaft 414. Pitmans 432 and 434 will thus be driven, moving rod 436 in a reciprocating manner. As rod 436 is moved the handle bar support member 448 will likewise be moved, causing the handle 'bars secured thereto to be operated in a fashion similar to that illustrated in FIG. 6. The seat post guide tubes 438 and 440 will likewise be driven through the linkage 464 and 462 and the seat (not shown) will be moved in opposition to the handle bar structure.

The embodiment last described permits the operating mechanism to be constructed in a somewhat smaller or compact space due tothe fact that smaller clearances are required. Also, the use of the two pitmans 432 and 434 reduces the size and strength of materials needed due to the duplicate driving system, and the preferred manner of mounting handle bar support member 448 on rod 4-36 permits some lateral play in the device without inducing unnecessary stresses to the parts, tending to cause premature failure of the driving mechanism. It will be seen from the foregoing description of the various embodiments described that the bicycle type exercisers of the invention are relatively simple in operation as compared to prior art devices, and improved drive means are disclosed in the various embodiments which reduce construction costs and result in improved efficiencies and movements.

Also, in each instance the framework and all the moving power driven parts except for the handle bars, the seat and the foot pedals can be enclosed within suitable housings, preferably made of light weight plastic mate rials, which reduces the possibility of injury by the user by inadvertently catching the limbs or clothing within the moving parts. Such a housing and construction not only provides these safety features, but as a result of this the necessary manufacturers liability insurance and the like can be substantially reduced, resulting in still further cost savings. Also, each of the embodiments can be manually operated since the usual counter balancing structure has been eliminated.

While the invention has been described in connection with specific embodiments, it will be evident to those skilled in the art that various modifications of this invention can be made or followed in the light of this description and discussion, without departing from the spirit of the disclosure or the scope of the claims.
